Environmental policy and ‘double dividend’ in a transitional economy

Although the environmental benefit from implementing a climate tax is usually realized, the economic dividend still remains a controversial issue warranting further research. This is because the impact of an environmental policy on an economy-wide system will depend on factors that differ from one region to the next. In this paper, we develop a static CGE model for Liberia that is capable of analyzing both a uniform and a partial carbon tax policy. Under the uniform policy instituted to ensure mitigation in the range of 20–50%, an economic dividend is found for energy, employment, and welfare. In particular, energy consumption increases by between 5 and 15.5%, respectively. Interestingly, under a second best policy which exempts economically strategic sectors from the tax, no economic dividend is found for all three variables. This time, energy use declines by between 2 and 9%. These suggest that a uniform environmental tax policy is a more viable option for Liberia, in particular, as it does not only generate economic dividend for employment and welfare, it also incentivizes Liberia's adoption and use of renewable energy technologies. In general, based on the results obtained, further conditions for the feasibility of a double dividend are proposed.
